    O carcinoma escamocelular (CEC) é tipo histopatológico mais comum do câncer de boca, ocupando o 8º lugar em incidência no Brasil. O sítio mais acometido é a borda lateral de língua, causado principalmente pelo alto consumo de tabaco e álcool, e o seu diagnóstico tardio é uma das principais causas de morbimortalidade elevada entre a população. Este estudo visa analisar o perfil dos pacientes portadores do CEC oral numa população do Espírito Santo (ES), de acordo com suas características sociodemográficas, clínicas e itinerária. Trata-se de um estudo transversal, coletado através de prontuários de pacientes submetidos a tratamento para o CEC oral no período de 2015 a 2023 em um centro de referência. Análise descritiva, Teste de Qui quadrado e Exato de Fisher foram utilizadas para análise das variáveis. Intervalos de tempos foram definidos para a investigação itinerária, bem como serviço ofertado e completude dos dados. Foram obtidos 48 casos, predominantemente homens (n=33, 68,7%), idade avançada (42 a 95 anos, média 60,7), pardos (n=33, 68,7%), tabagistas (n=19, 39,5%) e etilistas (n=21, 43,7%), com ensino fundamental incompleto (n=15, 31,2%). A maioria (n=29, 51,7%) das lesões estavam em língua, ulceradas e nodulares (n=26, 54,1%; n=10, 20,8%). A cirurgia foi o tratamento mais usado (n=35, 72,9%), e o serviço público o mais ofertado na consulta inicial (n=44, 91,6%) e tratamento (n=47, 100%). O intervalo da detecção da lesão pelo paciente até procurar atendimento em saúde obteve mediana de 6 (de 1 a 48) meses. O intervalo até o diagnóstico obteve mediana de 0,3 (de 0 a 65,7) meses, e o intervalo até o início do tratamento foi de 1 (de 0 a 15,8) mês. Houve associação entre pardos (p=0,04) e hipótese clínica de CEC (p=0,04) com o menor período de intervalo do paciente (0 6m), além da associação entre estágios iniciais I e II e tratamento cirúrgico (p=0,04). O perfil dos pacientes diagnosticados com CEC no ES evidenciam um padrão clássico e demonstram a relevância do serviço público. Os intervalos de tempo atendem a lei brasileira e seu estudo pode direcionar para políticas preventivas

    The KACE instrument (Knowledge, Attitudes, Access, and Confidence) was developed to assess outcomes of Evidence-Based Practice (EBP) training in Dentistry. This study aimed to carry out the translation, cross-cultural adaptation, and measurement property analysis of the KACE for Brazilian Portuguese. The process followed eight steps: 1) independent translation by two bilingual translators; 2) synthesis of the translations into a consensus version; 3) back-translation by two independent translators; 4) expert committee review to produce the pre-final version; 5) pre-testing with the target population (2nd semester undergraduate students); 6) administration of the tests (pre-training, post-training, and retest); 7) submission of the adapted version to the original developers; and 8) evaluation of measurement properties. The study was conducted with a sample of 124 participants (75 undergraduate students, 35 graduate students, and 14 experts) from the Federal University of Espírito Santo (UFES), University of Brasília (UnB), and Federal University of Santa Catarina (UFSC). Analyses demonstrated that the Brazilian version of the KACE showed adequate content validity, with some necessary adjustments in specific items identified through confirmatory factor analysis: item Q6 from the “Critical Appraisal Knowledge” scale, items Q7 and Q8 from the “Attitudes toward EBP” scale, and items Q1 and Q2 from the “Access to Evidence” scale. Internal consistency was considered acceptable, especially in the “Confidence in Critical Appraisal Skills” scale (Cronbach’s α ranging from 0.7075 to 0.9261). Test-retest reliability was satisfactory, with intraclass correlation coefficients ranging from 0.52 to 0.81. The instrument demonstrated discriminant validity by differentiating experts from undergraduates across all scales. Responsiveness was confirmed, with a significant increase in scores after the educational intervention (p < 0.05). It is concluded that the Brazilian version of the KACE presents evidence of validity and reliability, representing a promising tool for assessing competencies in evidence-based practice within the Brazilian dental context.

    Análise comparativa da temperatura gerada por diferentes designs de brocas em osteotomia para implantes dentários : influência da reutilização
    (Universidade Federal do Espírito Santo, 2025-07-16) Batista, João Pedro Oliveira de; Ramos, Umberto Demoner ; https://orcid.org/0000-0002-3759-1364; http://lattes.cnpq.br/7171760362653486; https://orcid.org/0009-0006-7011-9156; http://lattes.cnpq.br/9326566521319765; Andrade, Valdir Cabral ; https://orcid.org/0000-0002-1680-2855; http://lattes.cnpq.br/8411428235547363; Borges Filho, Fausto Frizzera ; https://orcid.org/0000-0002-0027-6686; http://lattes.cnpq.br/1222141128228079
    This study evaluated the influence of drill geometry and progressive reuse on heat generation during osteotomy for dental implant placement. Two drills from the same manufacturer were compared: the Epikut® (cylindrical design) and the Strong SW® (conical drill design), using polyurethane blocks simulating type III human bone density. Drilling was performed without irrigation, and thermal monitoring was conducted using infrared thermography. The Epikut® drills demonstrated thermal stability over up to 30 reuses, with no significant increase in final mean temperature (p = 0.197). For example, the Epikut 2.0 mm produced mean temperatures of 45.15 ± 0.39 °C (1-10 uses) and 44.87 ± 0.89 °C after 30 uses. Other Epikut drills (2.7 mm, 3.0 mm, and 3.3 mm) remained below 35°C on average. In contrast, the Strong SW® drills showed a progressive and statistically significant increase in temperature with the number of reuses (p < 0.001). The Strong SW 2.0 mm, for instance, increased from 30.93 ± 0.92 °C (1-10 uses) to 36.11 ± 6.43 °C after 30 uses. The Strong SW 3.05 mm rose from 17.71 ± 4.17 °C to 33.55 ± 5.34 °C. The results suggest that the tapered design of the Epikut® drill promotes better thermal dissipation and greater safety for reuse, while the cylindrical design of the Strong SW® poses a higher risk of bone overheating after multiple reuses. These findings highlight the importance of appropriate instrument selection and strict control over the number of uses to preserve bone viability and ensure successful osseointegration

    O heterocontrole da fluoretação da água de abastecimento público na percepção dos trabalhadores da vigilância no Estado do Espírito Santo
    (Universidade Federal do Espírito Santo, 2025-07-10) Porto, Ana Carla Layber; Esposti, Carolina Dutra Degli; https://orcid.org/0000-0001-8102-7771; http://lattes.cnpq.br/7465412734380334; Pacheco, Karina Tonini dos Santos; https://orcid.org/0000-0002-4687-6062; http://lattes.cnpq.br/1634767264856221; https://orcid.org/0009-0009-0519-7897; http://lattes.cnpq.br/0871440037404271; Frazão, Paulo; https://orcid.org/0000-0002-3224-0020; http://lattes.cnpq.br/0336022787699316; Oliveira, Adauto Emmerich; https://orcid.org/0000-0002-9679-8592; http://lattes.cnpq.br/1534956621971641
    Water fluoridation for human consumption is the most relevant public health measure due to its proven effectiveness in controlling dental caries. The environmental health surveillance sector in municipalities is responsible for the external monitoring (heterocontrol) of water fluoridation, ensuring optimal fluoride levels in the water supply, promoting oral health among the population, and minimizing associated risks. Several failures in the heterocontrol process have been reported. This study aimed to assess the perceptions of environmental health surveillance workers regarding the heterocontrol of public water supply fluoridation in the state of Espírito Santo, Brazil. A qualitative approach was adopted, involving ten environmental health surveillance professionals from nine municipalities of varying population sizes across the three health regions of Espírito Santo (Brazil). Individual interviews were conducted using a semi-structured script, recorded, and fully transcribed. Thematic Content Analysis was performed following Bardin's methodology. Heterocontrol of water fluoridation was recognized as important for water quality, although it was not carried out by eight of the interviewees. Training and state-level support were identified as facilitators of water quality surveillance, whereas lack of supplies and transportation, work overload, staff turnover, and insufficient training on fluoridation and its monitoring were reported as barriers. Positive perceptions of water surveillance work predominated, highlighting its social relevance. Negative perceptions stemmed primarily from excessive workloads and lack of training, the latter being the most frequently cited area for improvement within the Vigiagua Program. It is concluded that heterocontrol of fluoridation was only marginally associated with water quality, and that effective surveillance work depends on the provision of adequate working conditions for monitoring fluoride levels, ensured by health managers, including permanent education programs. In this way, water surveillance will become more effective, integrating fluoridation as an essential component of water quality.

    Oral cancer represents a serious public health issue in Brazil, characterized by high morbidity and mortality rates, largely due to late-stage diagnosis. Primary Health Care (PHC), as the preferred entry point to the Brazilian Unified Health System (SUS), plays a strategic role in the early detection of the disease, particularly through the work of dental surgeons. This cross-sectional study aimed to identify the main barriers to the early diagnosis of oral cancer within the PHC network in the state of Espírito Santo, Brazil. A structured questionnaire was applied to 248 dental surgeons, alongside an analysis of diagnostic support infrastructure data. The findings revealed low service resolvability, evidenced by the limited performance of biopsies among PHC professionals (16.13%), a high rate of insecurity in diagnosing potentially malignant lesions (64.5%), and lack of knowledge regarding institutional referral pathways. Among professionals who reported limited knowledge and low confidence in diagnosing oral potentially malignant disorders, 47.9% stated they did not feel capable of performing a biopsy (p < 0.001). These results suggest that limited practical training and structural deficiencies compromise the effectiveness of PHC, highlighting the need for integrated continuing education initiatives, expansion of diagnostic support networks, and stronger coordination across levels of care.
